Final answer:
If the telephone at the swimming pool is not working, it is best to keep the pool closed until it is repaired. Having a working telephone is important for the safety of the patrons, as it allows for emergency calls to be made. While having a cell phone can be helpful, it should not be relied upon as the primary means of communication in a public swimming pool setting.
Step-by-step explanation:
If you arrive at your swimming pool and realize that the telephone is not working, the best course of action would be to keep the pool closed until the telephone is repaired and working. This is because having a working telephone is crucial for the safety of the patrons. In case of emergencies, a telephone is necessary to call for help, such as contacting emergency services or lifeguards.
Allowing patrons into the pool without a working telephone could result in potential danger if an accident or emergency were to occur. Without a way to call for help, the situation could escalate and put people's lives at risk.
If you have a cell phone, it can be helpful as a backup communication device. However, relying solely on a cell phone for emergencies in a public swimming pool setting is not recommended. The pool management should prioritize the repair of the telephone to ensure the safety of everyone using the facility.
